The plurality of pixel units are in an arraystructure. The pixel units include pixel electrodes 141. The secondsubstrate 20 includes a second base substrate 21 and a common electrodelayer 22 formed on one side of the second base substrate 21 close to thefirst substrate 10, and the common electrode layer 22 is provided withat least one common electrode (not shown in FIG. 1).

When in image display, a scan signal is sent to each scanning line insequence, such that a data signal can be transmitted to the pixelelectrodes 141 in the pixel units in the first substrate 10 by the datalines 13. Meanwhile, a common voltage signal is provided for the commonelectrode, such that an electric field for controlling deflection ofliquid crystal molecules is formed between the pixel electrodes 141 andthe common electrode. Under the action of such electric field, theliquid crystal molecules are deflected, and further a display picture isgenerated.

Continuing to refer to FIG. 1, in an actual working process of thedisplay device, coupling and crosstalk phenomena will occur between thedata lines 13 and the common electrode layer 22. For example, anelectric field E1 is formed between the data lines 13 and the commonelectrode layer 22, and due to the existence of the electric field E1,deflection angles of the liquid crystal molecules nearby the data lines13 will be effected, as a result, the display device has the phenomenaof signal crosstalk and uneven display, and a display quality of thedisplay device is affected.

In view of this, the embodiment of the present application provides adisplay panel, to improve a display effect of the display device.
